CISCO-SIP-CALLS-MIB
AI MIB Summary
The CISCO-SIP-CALLS-MIB enables monitoring of active Session Initiation Protocol (SIP) call sessions, user agent states (UAC/UAS), and media forking configurations on Cisco SIP-enabled network devices. It provides protocol-specific counters and status variables to track call establishment, modification, and termination events defined in RFC 3261.
The Cisco Session Initiation Protocol (SIP) Calls MIB module is designed to provide protocol-specific information on SIP calls which are currently active. SIP is an application-layer signalling protocol for creating, modifying and terminating multimedia sessions with one or more participants. SIP is defined in RFC 3261 (June 2002). The endpoints in a SIP communication are called user agents. A user agent is an application which contains both a User Agent Client (UAC) and a User Agent Server (UAS). A UAC is an application that initiates a SIP request. A UAS is an application that contacts the user when a SIP request is received and that returns a response on behalf of the user. This MIB module provides information on SIP calls and the user agents initiating these calls. Also, it provides a way to manage media forking of SIP calls.

ciscoSipCallsMIBThe Cisco Session Initiation Protocol (SIP) Calls MIB
module is designed to provide protocol-specific
information on SIP calls which are currently active.
SIP is an application-layer signalling protocol for
creating, modifying and terminating multimedia
sessions with one or more participants. SIP is defined
in RFC 3261 (June 2002).
The endpoints in a SIP communication are called user
agents. A user agent is an application which contains
both a User Agent Client (UAC) and a User Agent Server
(UAS). A UAC is an application that initiates a SIP
request. A UAS is an application that contacts the
user when a SIP request is received and that returns
a response on behalf of the user. This MIB module
provides information on SIP calls and the user agents
initiating these calls. Also, it provides a way to
manage media forking of SIP calls. MODULE-IDENTITY .1.3.6.1.4.1.9.9.995 |
